Microservice Meltdown
SRE vs Chaos on a 5-service DAG. Real circuit breakers, OOMs, retry storms, load shedding — the engineering-interview vocabulary, live.
MultiplayerReliabilityCircuit BreakersChaos Gossip Protocol Virus
Anti-entropy gossip across a 10-node network. Propagator spreads TRUTH; Attacker forges Byzantine FALSE. Version vectors, three topologies.
MultiplayerDistributedCRDTByzantineBGP Routing Hijack
Two ISPs on a 9-AS simulated internet. AS-path prepend, deploy RPKI ROAs, hijack a sub-prefix. Pakistan Telecom 2008 replay included.
MultiplayerNetworkingRPKICTFTerminal Escape
Asymmetric CTF. SecOps rigs a sandboxed Unix box; the Attacker tries to print a flag they can't read. Real shell — pipes, redirects, symlinks.
